These studs are a nod to simple, they are tiny, each one solid. To make these I ball up the silver on the end of the wire, then flatten the ball into what you see here! Some are left like little mirrors, others I did some simple patterning on.
925 Silver
They come with hand made backs, which fit the adjustable posts.
The backs click on just like any studs you are used to, then you can twist them tighter or looser on your ear for a perfect, comfortable fit.
